Westhinghouse EA3050 - 50A, 3-Pole, Circuit Breaker

Overview
The Westhinghouse EA3050 is a 50A, 3-pole circuit breaker designed to deliver dependable overcurrent protection in power distribution environments. Its 3-pole configuration is ideal for three-phase systems, making it a practical choice for panelboards, switchboards, and control panels across industrial, commercial, and OEM applications.

• Current rating: 50A
• Poles: 3-Pole
• Breaker type: Circuit Breaker

Why this 3-pole design matters
In three-phase installations, a 3-pole circuit breaker provides balanced protection across all conductors, helping prevent uneven loading and ensuring reliable shutoff during faults. The EA3050 is engineered to integrate smoothly into standard multi-pole slots in distribution panels and motor control centers, simplifying replacement and upgrade projects without sacrificing performance.

Ideal applications

• Industrial facilities with three-phase equipment and motor loads
• Commercial electrical rooms requiring robust branch-circuit protection
• OEM equipment enclosures and control panels needing a reliable 50A protection device
• Motor control centers and distribution panels where consistent, safe interruption of fault currents is critical

Key benefits and practical impact

• Targeted protection for three-phase circuits: The 3-pole configuration ensures synchronized interruption for all phases, reducing risk of equipment damage during faults.
• Clear 50A protection threshold: Precise current limiting helps guard motors, drives, and feeders from overloads while supporting coordinated protection schemes.
• Easy integration: Designed to fit standard panelboard and switchboard architectures, simplifying installation, replacement, and inventory management for maintenance teams.
• Durable for demanding environments: Built to deliver reliable performance in everyday industrial and commercial use, contributing to lower downtime and safer operation.

Usage tips for best results
- Pair the EA3050 with compatible wiring and mounting accessories intended for 3-pole breakers in your panelboard or switchboard.
- When replacing an existing breaker, match the 3-pole format and current rating to maintain protection characteristics and trip behavior.
- Ensure proper electrical clearances and follow site safety practices during installation and maintenance to safeguard personnel and equipment.
